WTF, it’s all over, watch the ditches when your driving around, I find new spots by looking for tall plants that have gone to seed (easy to spot). Often, there are some shorter, edible stalks nearby. Once you find a location, you can check back for years. Some pics on this page showing what the tall ones look like:http://my.gardenguides.com/members/divaqs/blog/2007/04/30/Asparagus
